SUNSPOT MONITORING – JULY 8, 2018

No solar images were taken today, July 8, 2018, due to time constraints from some important institution-related errands.

Though the Sun is spotless at this moment, the unnumbered active region currently behind the eastern limb (not yet visible), about to rotate into Earth-view, produced some B-class flares over the past 24 hours.  The latest sunspot number (based on visual count and Wolf number calculation) is 0.  A huge eruptive hedgerow prominence at the northwestern and southwestern limb, as well as filaments including one at the southern portion, and the associated of the reappearing active region, were distinctively captured in H-alpha imagery.

Space weather agencies* forecast solar activity to remain at very low levels with chances B-class up to possibly isolated C-class flares, mainly from the appearing active region, in the next days. The extent of the frequency and intensity of the Sun’s activity will highly depend on the magnetic flux fluctuations happening in the visible ARs in the coming days. Close monitoring is being conducted by numerous space weather agencies for any significant development.
